put finger to keyboard and composed:

Does anyone know the date codes that Mallory uses on their electrolytic
caps a 1900ufd at 450v? Here's a couple of lines..
CGS192T450X5L3PH
235-8112K
Thanks

I have three screw terminal Mallory caps with the following markings:

MALLORY

30000MFD 15VDC
POS + 85C
MAX SURGE 20VDC
95661319
235-8102K

MALLORY
MADE IN U.S.A
TYPE CGS
29000MFD 15VDC
POS + 85C
MAX SURGE 30VDC
CGS293U025R4C3PH
235-8532K

MALLORY
MADE IN U.S.A
TYPE CGS
21000MFD 16 VDC
POS + 85C
MAX SURGE 20 VDC
CGS213U016R3L
362 8906 56699

They all date from around the early 80s.

Here they are pictured among Sprague caps of the same vintage:

I'd say that 8112 is a YYWW date code.
